Once you are finished, delete the initial files (lib.zip, install.php, setup.php, and enable_setup) from your web server. You won't need them anymore, and they grant visitors that are aware of these files' presence write access to your server.

Log in using the user account you have created during the setup of your site.

If your web server is unable to handle Zip files, the execution of install.php will fail. In this case, you have to extract the contents of file lib.zip manually on your computer, and transfer all extracted files (including directories and sub directories) to your web server.

If your web server does not support the default database settings either, you have to make the necessary changes manually using a plain text file editor. To do so, open file core/pool_base.php. Database storage is configured in the first couple of lines.

You also skip the installation if you just want to install additional sites beyond the first one. All sites can make use of the previously installed library. Note that you need the files setup.php and enable_setup to set up new sites. While setup.php is an executable script, enable_setup is a security control file whose existence determines whether installation or setup is permitted at all.
